HA420-40-200 Salvia miltiorrhiza extract, mother chrysanthemum oil Extract, lycopin Supercritical Co2 Fluid Extraction Device

Low Critical temperature suitable for extraction and purification of heat sensitive compound.Being capable to provide inert environment to avoid oxidation of products and affection of effective content of extracts.

Fast extraction speed, no toxicity, non-flammable, safe application and no pollution upon environment.

No residue of solvent, no nitrate and ions of heavy metal.

The Super Critical fluid technology is a new-type separation technology in modern chemical separation. The Super Critical extraction takes CO2 as the solvent. As CO2 fluid under Super Critical state has larger density and dielectric constant, larger dissolvability against substances, which can change abruptly when pressure and temperature change therefore it has not only the selection of dissolvability against substances, the separation of the solvent with the extracted substances is also easily. The Super Critical CO2 extraction is specially suitable for fine separation of different components, i.e. Super Critical fine distillation.

Take CO2 as the solvent to make extraction and purification upon a lot of products such as biological products, foodstuff and medicines.

1. Supercritical CO2 fluid extraction system was very good at thermal sensitivity natural product extraction, as we know, the tradition extraction method usually applied as steam distillation and fractionation, heating will break up thermo-sensitive material in natural product, destroy some active ingredient, SCFE system could working under a constant temperature or even low temperature condition for extraction and separation, keep the material in original characteristics.

2. CO2 as supercritical solvent, which could be recycling working in the whole system, with low energy consumption, non-pollution and accessible features.

3. The SCFE system could accomplish multi-function in one device, through extraction, separation, filtration and rectification; customer could finish different technical process according to different herbal material extraction condition, easy operation and maintenance.

Basic Flow:

1. CO2->extraction kettle->separation I-> separation II->return circuit
2. CO2->extraction kettle->separation I-> separation II->fine distillation column->return circuit
3. CO2-> extraction kettle-> fine distillation column-> separation I-> separation II->return circuit
4. CO2->extraction kettle->separation I-> fine distillation column-> separation II->return circuit

Extra flows can be increased according to technological requirement:

1. CO2->bottom of fine distillation column-> separation I-> separation II->return circuit, meanwhile raw material (liquid) ->continuous extraction of liquid material in the middle part of the fine distillation column(counter flow)
2. Separation I or separation II (separated substances) ->sub-pump->middle and upper parts of fine distillation column.

Combination Style:

1-extraction-1-separation, 1-extraction-2-separation, 1-extraction-2-separation-1-column, 2-extraction-2-separation, 2-extraction-2-separation-1-column, 4-extraction-2-separation, 4-extraction-2-separation-1-column and special combination can be customized as request.

Main Introduction : 

This device usually be used for material extraction under the high pressure and suitable temperature (solid or fluid), Changing conditions in the separator to parse out dissolved substances in order to achieve the purpose of separation. The device is mainly composed of : extractionkettle, Separate kettle, CO2 high-pressure pump, entrainer pump, cooling system, CO2 basin, exergy transfer system, purification system, flowmeter, temperature-controlled system, safety protection device and so on. Attached device and the system can meet the needs of the main system of supercritical extraction and flow chart of requirements

 Commonly, Supercritical fluid extraction device adopts CO2 as the extracting media. The advantages as follows:

1) Convenient in operation. Can be used widely.

2) With an excellent optional function. Extracts can be gained optionally by controlling the pressure and temperature.

3) Low operation temperature. Can be extracted near to the room temperature, especially fit for the extracting of thermo-sensitive elements. The possibility of oxidation when contact with oxygen and reaction when meet rays are eliminated. The natural flavor of the extracts can be kept.

4) Extracting media and extracts can be separated easily. No leftover of CO2 on the extracts after extracting operation.

5) CO2 is a nontoxic, flavorless, noncombustible and cheap compound and can be recycle used.

The better features of equipment after comparing with similar products at home and abroad:

1.CO2 can be recycled, and be equipped with return circuit which saves gas, ensuring that the pressure of extraction kettle can be reduced under 4MPa after working, also making the Min. discharging amount. Adopt new methods of fluid distribution uniform fluid distribution, which makes CO2 fluid and solute uniform contact to speed up the dissolved, shorten extraction time, increase production

2.It adopts new method and new technology which can make CO2 residual gas in a cylinder under the net weight 1.5 Kg.

3.Each kettle has function of measuring and controlling temperature system, which can   effectively control the temperature of the thermal inertia

4.Extraction cylinder adopts quick-opening structure which developed by our company. It opens very easily, sealing is reliable, and the repeatability is good when CO2 swelling. It can be use for a long time without having to replace the sealing ring, which effectively solved the difficult problem of o-rings event of CO2 expansion. 

5.Pressure adjustment valve of each kettle is good at high precision, small volatility, well stability.

6.security system of double pressure protection

7.All the kettles are equipped with safe valve, implementing the overflow protection when overpressure ; In addition, the kettle is equipped with electric contact pressure table. It is good at protecting through artificially setting maximum pressure, carrying out overpressure stopping pump function.

8.The mixer is given priority to the auxiliary pump, mix them with electric contact pressure gauge, Pointers can use upper and lower limits of system pressure protection, overpressure activity pointer to pointer exposure limit, when the pump stop working

9.Extraction cylinder device has manual controlling system and automatic controlling system, making the manual and automatic dissolve into an organic whole. So that the controlling precision is greatly increased and it can reach 0.5%, the purity of the extracted components is higher

10.The extraction time is artificial for humanized design. When the equipment stops working, it can make a sound to warm the workers.

11.Function of device is complete, such as supercritical fluid extraction, supercritical fine particles preparation, determination of solubility of the solute
